The invention relates to a gas turbine engine of the kind comprising a first turbine which drives the compressor and a second turbine which drives an output shaft, there being a gear assembly by which the two turbines may be inter-connected during part-load operation. In Fig. 1 the power plant is utilised in a vehicle, the power turbine 1 driving a hollow shaft 3 which carries a gear-wheel 4 which engages with intermediate pinions 8 rotatably mounted on fixed shafts 7, the pinions engaging an internal ring gear formed in the cylindrical member 10 which is formed integrally with an output shaft 11. The compressor-drive turbine shaft 5 extends through the hollow shaft 3 and carries a gear wheel 6 which engages with intermediate pinions 9 also rotatably mounted on fixed shafts 7, the pinions engaging an internal ring gear 15 which in full -load operation is freely mounted so that no load is transmitted from the compressordrive turbine 2. In part-load operation and during downhill running, the clutch 13 is engaged so that the ring gear 15 is secured to the ring gear 10 so that the compressor-drive turbine 2 acts also to drive the output shaft 11. The inner clutch member 12 is connected to the ring gear 15 by a gear connection 17. In Fig. 2 an epicyclic gear assembly is used, the power turbine shaft 3 having a gear 4 which engages with planet pinions 8 carried by a planet carrier 7 which is formed integrally with the output shaft 11, the planet pinions engaging a fixed ring gear 10. The compressor-drive turbine shaft 5 carries a gear 6 which engages with planet pinions 9 also carried by the planet carrier 7, the pinions 9 engaging a ring gear 15 which in fullload operation is free to rotate so that no drive is transmitted by the compressor-drive turbine 2. In part-load operation the clutch 13 is engaged so that the ring gear 15 is held fixed whereby drive is transmitted from the compressor-drive turbine to the output shaft 11.

Title: Process for the preparation of porous filamentary cellulose acetate
IPC: D01F2/28
Filed: 1960-06-03
Abstract: Porous filamentary cellulose acetate having a micro-rugose surface is made by diluting a solution of cellulose acetate with a proportion of a liquid precipitant miscible with the solution which proportion is only just insufficient to precipitate the cellulose acetate and introducing the resultant mixture in the form of a thin stream or multiplicity of streams into a stream or moving body of the same or another liquid precipitant or on to the surface of such a moving body of precipitant.  The cellulose acetate solution may be obtained from a cellulose acetylation process.  The precipitant may be water. The mixture and/or the precipitant may contain a precipitant-soluble surface-active agent.  A stream of the mixture may be deposited against a weir over which a stream of the precipitant is flowing at a rate exceeding the rate of flow of the stream of mixture.  The mixture may be deposited on to the surface of a rotating drum or moving band which surface is continually covered with a layer or a film of precipitant. The mixture may be deposited from one or more supply means adapted to reciprocate transversely or diagonally across the width of the surface of the drum or band.  The combined motions of the drum or band and the supply means may cause a mat of criss-cross filaments to form, a proportion of the filaments being lightly bonded together at points of intersection.

Filed: 1950-08-09
Abstract: 673,319. Valves. HANDELSBOLAGET TOUR AGENTURER G. TOUR & CO. Aug. 9, 1950 No. 19805/50. Class 135. A valve for controlling radiators has the co-operating flow-controlling members so formed that the heat output from a radiator bears a linear relation to the position of a control handle for the valve, and to this end the area of the valve opening is made to vary substantially according to the expression a, b<SP>n-1</SP> where a is the area of the smallest effective opening of the valve, e.g. when the control handle is set to the first division on an evenly calibrated scale, b is a constant depending upon the radiator, &c., and n is the degree of opening of the valve as read off the scale. In the embodiment shown in Figs. 1 and 3, a spring- pressed rotary disc valve member 26 has an edge 31 which coacts with an orifice 29 in a fixed disc 25 to control the valve opening. A pointer 14 carried by a handle 13 indicates the degree of opening on a scale 15. In a modification, Fig. 6, the control edge 31 of the rotary disc, which coacts with an orifice 29 of substantially rhombic shape, extends over about 300 degrees of the disc, and the latter is supported by radial arms 32, 33, 34. The pointer 14 may move between a fixed stop 37 defining the closed position of the valve and an adjustable stop 38. An angularly adjustable ring 35 on which the stop 38 is mounted has two scales, one marked O-V coacting with an index 40 and indicating the range of movement permitted the valve and another 0-10 for indicating the degree of opening of the valve. In a further modification, the pointer 14 moves over a fixed scale and an adjustable stop limits the degree of opening. In another embodiment, the valve member 56, Fig. 8, is of cylindrical form, either solid or hollow, and is ported at 57 to control .the rate of flow. A disc 55 completes the closure. The valve is actuated by a screwed stem 48 and a pointer 52 coacts with a scale 53. An adjustable stop, which may be locked by a nut 60 coacts with the pointer to limit the degree of opening permitted the valve.

Title: Multiplexing or demultiplexing networks
IPC: H01P1/213
Filed: 1973-04-26
Abstract: 1379725 Multiplex radio signalling WESTERN ELECTRIC CO Inc 26 April 1973 [28 April 1972] 19805/73 Heading H4L An arrangement is provided for multiplexing or demultiplexing signals in different frequency bands. As shown in Fig. 3, signals A and B in different frequency bands are supplied to input ports 1 of directional couplers or hybrid networks 10, 11, respectively, and the combined output is taken from output port 1 of a similar coupler 12. Signals applied to port 1 of the couplers divide between ports 2 and 4 as a function of the coupling factor and with 90 degrees phase difference, no output appearing at port 3. The couplers are connected together as shown, reflective cavity 31 being coupled via circulator 33 into the connection between ports 3 and 2 of couplers 10, 11 and reflective cavity 32 being coupled via circulator 34 between ports 2 and 3 of couplers 10, 11, respectively. Signal A is divided in coupler 10 between ports 2 and 4 and the portion at point I is passed by coupler 12 to the output, the remaining part of signal A being divided by coupler 11 between ports 2 and 4, the portion at port 4 appearing at II and being coupled to the output and the portion from port 2 being returned to coupler 10. The input B is split and combined in the output in similar manner. The resonant frequency of the cavities is selected to be midway between the bands A and B and the coupling factors of the coupling networks and the phase shifts introduced by the resonant cavities are proportioned so that corresponding signals in the frequency bands are combined in phase at port 1 of the coupler 12. With reversal of the direction of circulation of the signals, the network will separate signals of different frequencies received from a common source. In a modification, Fig. 6 (not shown), the circulators are replaced by directional couplers and additional reflective cavities. The system is stated to be an improvement on a prior arrangement using lengths of transmission line to provide the required phase shift.
